About this calculator
Rankine is the absolute version of Fahrenheit (0 °R = absolute zero). 0 °F = 459.67 °R; room temp 70 °F = 530 °R. Used in US/Imperial engineering thermodynamics. Kelvin is the absolute Celsius equivalent. Conversions: 0 K = −273.15 °C = 0 °R = −459.67 °F.
Frequently asked
Thermo equations need absolute temperature. Engineers using Fahrenheit prefer Rankine to avoid switching to metric.
